Class IV Rafting on the Arkansas River

What Class IV feels like

Class IV rapids are powerful and continuous, with big holes and waves that need precise boat handling. You'll paddle hard, and a swim here is a real swim.

The Numbers is our Class IV run: seven miles of nonstop rapids above Buena Vista. It's the next step after Browns Canyon for fit, confident paddlers.
